Modify the Gear & Make Construction

Based on my first failed experience of making an Epicyclic gearing plate, I modified the size of the small gears placed in the centre and made a back plate to hold the whole Epicyclic gearing plate in place, fixing the two small gears in the centre and rotating the outer gears to make the structure work.

At the same time, I combined the finished pattern of the optical illusion with the gearing structure to make the structure more interesting through the motion of the rotation.
